For years the sky condition in Hong Kong has became unbearably terrible for wide field astrograph, attached an old image of Orion taken back in Spring of 2001, now it's almost impossible to shoot similar one again with all the constant hovering dust and haze in the air, windlees or not!
hance me and some friends had to look for darker spot in Mainland otherwise we might just better off forget star gazing!
